fix: correct timeframe display in Bot Status for scalping strategies

- Add selectedTimeframes to automation status API response to show actual running timeframes
- Update Bot Status UI to display selectedTimeframes from API instead of local config state
- Fix issue where Bot Status showed '1h' instead of scalping timeframes '5m, 15m, 30m'
- Ensure selectedTimeframes are properly stored in database settings and retrieved in status
- Bot Status now correctly reflects the actual running automation configuration

UI Changes:
- Bot Status timeframes now shows: '5m, 15m, 30m' for scalping instead of '1h'
- Analysis Timer correctly shows 2-minute intervals for scalping strategies
- Status display is now synchronized with actual automation configuration

Backend Changes:
- Store selectedTimeframes in automation session settings
- Include selectedTimeframes in getStatus() API response
- Enhanced interval detection to support settings-based timeframes
